Sources & further reading:
At this very second, you are on a narrow ledge between life and death. You probably don’t feel it, but there is an incredible amount of activity going on inside you. And this activity can never stop.
Picture yourself as a slinky falling down an escalator moving upwards - the falling part represents the self replicating processes of your cells, the escalator represents the laws of physics, driving you forwards. To be alive is to be in motion but never arriving anywhere. If you reach the top of the escalator there is no more falling possible and you are dead forever.
Somewhat unsettlingly, the universe wants you to reach the top. How do you avoid that and why are you alive?

    Living organisms are open systems and constantly exchange matter and energy with their surroundings, keeping internal entropy low by exporting higher entropy to their enviroment. TL,DR: You are allowed to live because you are promoting the transformation of the cosmos into a barren wasteland

    The cells (and all living entities) avoid entropy by staying out of thermodynamic equilibrium, which would bring a constant, and thus dead, state. I hope someday you will make a video about Gibbs free energy.

    My professors have given me so many different texts about the definition of entropy, however because of its complexity none of them succeeds in actually fully define it. I look forward to that video. (Sorry if i make mistakes, english is not my mother tongue)
